Pcos & the longer wait

I have pcos so my cycles vary in length. They can go anywhere between 28-41 days, once it was even longer than that. I got pregnant last year & didn’t get a bfp until cycle day 41 - at that time, most of my cycles were 40-41 days long. I gave birth in February (sadly lost my son a few days later due to a rare condition he was born with that didn’t present itself until after we were discharged from the hospital). Since giving birth, my cycles have been 35-36 days long. We are ttc & my current cycle has lasted 39 days so far. It seems actually late & I’ve been feeling symptoms, but I haven’t gotten a bfp yet. I know my symptoms can be pms, but the headaches & dizziness feel more than usual. What do y’all think? Should I test again in 2 days? It’s so hard to know when to test if you have pcos :(
